Oceanário de Lisboa

The Oceanário is the best indoor option in Lisbon for families and for wet days, but it is not a quick add-on. It sits about 7 km north-east of the Jardim do Tabaco terminal in Parque das Nações, so budget roughly half a day: 30 to 40 minutes each way plus 90 minutes to two hours inside, which is the museum's own estimate for an average visit. To get there, walk about 10 minutes to Santa Apolónia station and take a suburban train to Oriente, then walk about 15 minutes through Parque das Nações to the aquarium on the waterfront. A taxi or ride-hail from the terminal takes about 15 minutes in normal traffic and is often the simpler choice for a group of three or four. The core of the visit is the central tank, which you see from windows on two floors, surrounded by four smaller habitats representing the North Atlantic, Antarctic, temperate Pacific and tropical Indian oceans. The sea otters and penguins are above water, so you see them at the surface as well as below it. Temporary exhibitions (currently Sea Monsters and Submerged Universe) are included in the standard ticket. Takashi Amano's Forests Underwater exhibition closes on 30 September 2026. Prices depend on your entry slot: adults pay 29.90 euros between 10:00 and 11:30, 27.70 euros from 12:00 to 15:30 and 25.50 euros from 16:00. Buying online gives a further 5 per cent discount. Late morning, on weekends and on rainy days are the busiest times; if your ship leaves late, a 16:00 slot is both cheaper and quieter. There are cafés and a restaurant on site, and paid lockers on floor 0 for small bags.
